Ethereum 2.0 coordinator Danny Ryan said that the release of the Ethereum 2.0 public test network will take at least two weeks. Ryan said that a new specification version 0.9 has been released, but some changes are needed to raise it to 0.9.1. He hopes to complete these changes this weekend, stating that these changes will need to be made first before any "carefully scheduled" test network comes out. Adrian Manning of Ethereum 2.0 client Lighthouse said he is working hard to build a public test network with a focus on ETH1 connectivity. Ryan himself released a list of test network tools.
